ZERO Code Energy Calculator

To generate a building’s estimated energy consumption, and the renewable energy required to meet the ZERO Code, first elect the pathway for meeting ASHRAE Standard 90.1-2016 – prescriptive or performance – and then enter information about your building and any on-site solar PV system(s). Click Generate Results to view the the Estimated Building Energy Consumption and/or off-site Renewable Energy Requirements. For detailed instructions on how to complete each section of the ZERO Code, visit the User Guide.

Note: The ZERO Code software Energy Calculator currently includes weather and solar files for 2,500 cities worldwide. Thousands of additional cities with weather and solar files will be made available in the Calculator soon.

The ZERO Code – an Architecture 2030 initiative – is a national and international building energy standard developed for adopting jurisdictions. The ZERO Code incorporates current and cost-effective energy efficiency measures with on-site and/or off-site renewable energy resulting in zero-net-carbon buildings.

Architecture 2030, in offering the ZERO Code, accepts no responsibility or liability for the accuracy of the inputs, assumptions, default values, and results estimated by the ZERO Code Energy Calculator, or for the design and performance of buildings utilizing the ZERO Code.
